A recent report confirmed that the International Space Station has managed to get three more crew members. The new members include NASA astronaut Thomas Marshburn, Cosmonaut Roman Romanenko and Canadian astronaut Chris Hadfield.

It was on Wednesday morning that they aboard a Russian Soyuz from Kazakhstan, and had to travel for two days before reaching the ISS at 11:37 am on Friday.

With this, the International Space Station's Expedition 34 gets its full team. The new members, who are all veteran of space station missions, would be staying there until May 2013. Once the current crew members Kevin Ford, Oleg Novitskiy and Evgeny Tarelkin, leave, Expedition 35 would be started, spearheaded by the command of Hadfield.

It has further been told that NASA is aiming to test colour-changing lights on the International Space Station (ISS) in order to support astronauts. It is expected that this step would be able to deal with the concerns like insomnia which astronauts face.

There have been reports concerning sleeping problems among space travelers. "On some space shuttle missions up to 50% of the crew take sleeping pills, and, over all, nearly half of all medication used in orbit is intended to help astronauts sleep", said NASA in 2001. There are expectations that the test would happen in 2016.
